Their molecules contain unpaired electrons, which are mobile

Their molecules contain loosely held electrons which get free
under the influence of voltage

The molecules break up into ions when a voltage is applied

The molecules are broken up into ions when the electrolyte is
fused or is dissolved in the solvent

They are unstable

The water dissolves it

The force of repulsion increases

The forces of electrostatic attraction are broken down by water

Forms complex ions in solution

Gives ions only when electricity is passed

Possesses ions even in solid state

Gives ions only when dissolved in water

Are partially ionized 

Do not ionise

Ionise almost completely

Form polymers

Dissolve readily in water

Conduct electricity

Dissociate into ions at high dilution

Completely dissociate into ions at all dilutions

Copper sulphate

Sugar

Common salt
